made longer and projects downward into a boss 2O that extends into the casing 1 through the opening 3 and has in its lower end a contact brush 21 normally forced outward by a spring The rotor is hollow at one end vto tit around a bearing at the rear of the casing 1, and this rotor may have a pair of flanges 24 and 25 between which is a slip ring 26 which males contact with the brush 2l. This brush will be secured to one terminal of the secondary windings of the coil, the other terminal being` grounded, and the llanges 24 and 25 will have conductor arms 27 and 28 respectively spaced a suitable numbei" of angular degrees apart to come into operative position by turns with the distributor terminals to be described later, insulatably supported in the side oil the casing 1.

rlhe front end of the shatt- 2 is supported in another bearing 29 at the center otfa cap 36 which closes the ront'ot the casing 1. The inside of this casing at the front has an anl nular shoulder 31 against which the interrupter plate 3 abuts and the cap 30 nts against the outer face of this plate around the cirrllhe conductor element 16 eX- tends down behind this plate and is joined 'thereto by a spring 32 which presses against the rear of the plate. 'lhis spring is secured to the element 16 by a screw 33. tion or tongue 34 is struck up from the plate and bent outward and is perforated to carry a screw 35, the end of which carries the lined contact ot the interruptor. A lever 36 ot insulation is mounted on a pivot 37 on the plate 6 and attached to this interruptor lever is a spring 38 carrying the movable Contact of the interruptor, this spring 33 being anchored to an insulated projection 39 on the plate 8. The other 'terminal ot the primary will be con nected to the spring 39. n the adj-acont end et' the shaft 2 is a cam member 40 adapted to engage the end of the interrupter lever 36 periodically and move it to separate the con tact and that on the spring 38.

rlhe terminals of the primary coil 11 are united one to the spring 38, and the other to the contact element 35, and one ot these parts must or course be insulatably mounted on the plate 8.

ylhe governor between the circuit interrupter and the distributor rotor 6 comprises a plate `41 rigid with the rotor and the shaft 2. Surrounding the shaft in front of this plate 4l is a spacing sleeve 42 which separates the plate from a second plate 43. Governor weights indicated at 44 are mounted on one or more pivots 45 affixed to the plate 43.

These governor weights have studs 46 whichV engage slots 47 in the plate 41 and they also have studs 48 which pass through openings 49 in the plate 43 to engage springs 50 which are affixed to the upturned ends 51 of a plate I 52 by means of suitable screws. The plate 52 may be affixed to the plate 43 by screws or Il proj ecother suitable means. Made rigid with the plate 43 is a sleeve 53 that carries the cam 40 and this cam sleeve may have a collar 54 which is tightly gripped by the plates 43 and 52 so that the cam and the governor plates 43 and 52 are lirmly connected. Obviously whenever the speed rises the governor weights will ly outward and shift the plates 4l and 43 with respect to each other. This movement of the weights being resisted by the springs 50. rEhe slots 49`may have any suitable shape.

The plate 8 has an opening 55 adjacent the screw 33 to permit this screw to be removed and the plate 6 taken out. At this lower side, the cap 30 has an opening 56 and at 57 is a cover for the cap 30, this cover being held in place by a suitable element 58 which may be a bail having its ends pivoted in yopenings in the sides of the casing. The rim of the cover engages a shoulder 59 around the outside of the cap 30 and the bail 58 thus holds plate 8, cap 30 and cover 57 in place.

The opposite sides or' the casing 1 adjacent the rotor 6 have openings to receive plates o'l l.

insulation 60 each ol which carries distribut r terminals 61 in two pairs, one pair being in the transverse plane ol the tlange 25 and the oth-er in the plane of the flange 24. The

J5 'four terminals 1n each transverse plane are spaced equidistantly apart. The rotor terminals 25 and 27 are about half as iarapart as the terminals of each pair. Hence the arms 27 and 23 will close the circuit alternately to theditlerent sparkplugs of the engine. The members 60 can be removed at will to inspect the terminals 61. f i" In the rear of .the casing is a. hollow duct 63 having an inlet element 64, and surrounding `t-he acent end of the shattf?l is a bushing 62, the lower end of the bore 63 terminating in chamber 65 to receive lubricant. The bore 63 continues through the lower halt of the casing wh'ere'it contains a piece of wicking 66 held by a spring 67V against the shaft 2. The bottom oit this duct is closed by a plug 68. ln the cap 30 in the frontot the casing is a bearing 69 for the front end of the shaft 2.

As the shaft 2 rotates the primary circuit will be broken as many times in each revolution as there are terminals 61 and the dis-V tributor arms 27 and 28 will close the circuit to the distributor terminals 61 in two transverse plates thereof by turns. 'It will be noted that all of the connections from the coil to the timer are made through the plate 4 and are enclosed in the housing. The rotor is at the rear of the casing because it seldom requires attention, while the circuit breaker points are in front where they can easily be inspected and kept in condition by taking oft" cover 57 rlhe plate 8V may have a hole large enough to permit the removal by slipping it over the cam 40 so as to give access to the ill@ 'ming member secured tothe'iinside OfftheCVe; t vth f )ov v, v and comiectedto the', coil -at one endnand'rto o llfe Y. e'f efmga a# ate'carrylngia' 'one of the contactson the timer plate -Onjthe L Xe. an :at Inova e Contact m 'the asmgra opposite end;
